使用低成本遥控潜水器和水下摄影测量技术对希腊米洛斯岛Paleochori湾周围的浅热液喷口进行三维重建。通过交互式水深测量模型描述通风场的特征，该模型是由双光栅模式下飞越感兴趣区域的机载相机拍摄的静止图像生成的。首次利用气动力探测器对米洛斯火山的浅部喷流场进行了主动探测。成功地测量了一些地区，并使用分辨率约为10厘米的SfM摄影测量法重建了水深。对各种海底生境进行了调查，由此产生的地形模型将作为基线，进一步描述喷口系统的特征以及与矿物沉积有关的任何不断演变的海底形态
The use of low-cost, Remotely Operated Vehicle (ROV) and underwater photogrammetry techniques for 3D reconstruction of shallow hydrothermal vent sites around Paleochori Bay, Milos Island, Greece. Characterising venting fields through interactive bathymetry models produced from still images taken from camera onboard ROV flown over areas of interest in double raster pattern. First time the shallow venting fields on Milos have been actively surveyed using ROV. Areas were successfully surveyed and the bathymetry was reconstructed using SfM photogrammetry with a ~10 cm scale resolution. A diverse range of benthic habitats were surveyed and the resulting topographic models will act as a baseline, providing further characterisation of the vent systems and any evolving seafloor morphology associated with mineral deposition
